kernel/relay.c: change return type to vm_fault_t

Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. commit 1c8f422 ("mm: change return type to vm_fault_t") Link: http://lkml.kernel.org/r/20180510140335.GA25363@jordon-HP-15-Notebook-PC Signed-off-by: Souptick Joarder <[email protected]> Reviewed-by: Matthew Wilcox <[email protected]> Reviewed-by: Andrew Morton <[email protected]> Cc: Eric Biggers <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
